upon an axle 15.- As shown in Fig. 1, the axle 15 registers with, and, in the best embodiment of my invention, is inclosed by and journaled in across-bar 16 through-which it extends. The cross-bar 16 is preferably a sleeve s uared in cross-section to form a firm support or other parts hereinafter described.

17 indicates a tongue, which is supported by means of a cross-bar 18 and braces 19.

The braces 19 are connected by suitable supports 20 with the cross-bar 16.

The hub of each of the carryin' -wheels 14 is provided upon its inner face wit 1 a circular set of ratchet-teeth- 21. r

v 22 indicates a cylindrical block which is keyed to one end of theaxle 15. As is best shown in Fig. 6, this cylindrical block is pro- .vided with an arm 23 upon which is pivoted a pawl 24, which, by means of a spring 25, is caused to engage with the ratchet-teeth 21 in such a way that when the machine is driven forward the rotation of the carryingwvheel 14 will cause the block 22 to revolve and "rotate the axle15; and when themachine is backed or the wheel 14 rotated in the other direction the parts will ratch back, so that the axle 15 will not be rotated.

26 indicates a gear, which is provided with a hub 27 and is keyed or otherwise secured to the other end of the axle 15. The hub 27 is provided with a spring-actuated pawl 28,

which engages with the ratchetteeth 21 of I I the other carrying-wheel 14 in the same manner,that is to say, in such a way that when the machine is driven forward the pawl 28 will engage with the teeth 21 andcause the axle 15 to rotate; but when the 'Wheel 14 is rotated backward, b backingthe machine .or otherwise, the paw will ratch back over the teeth. The rear surface of the gear 26 is recessed, as shown in Figs. 3 and 4.

29 indicates a supporting plate which'is secured at its front edge, by means of a clip 29*, to the bar 16. The rake-frame of the machine consists of end-bars 30-31, a front bar 32 and a rear bar 33. The end bar 30 is bolted or otherwise secured to the plate 29. The front bar 32 is bolted .atits-forward end above the plate'29. The rear bar 33 is secured at its forward end to the end bar 30, by means of a strap 34. The fron't'bar 32 and rear bar 33 are bolted or otherwise secured to the end bar 31.

35 indicates a beam, the front end of which is secured by a clip 36 to the cross-bar 16.

fork 47.

37 indicates a bracket which is supported by the front bar'32. The beam 35 is bolted to the bracket 37.

38 indicates a trussbrace,'which passes over the bracket 37 between it and the beam 35, and its ends are bolted to the front bar 32 near the extremities of said front bar 32.

39 -40 indicate braces which are secured to the rear bar 33 and to the beam 35.

41 indicates a sleeve which is secured in suitable su ports 4243 carried, respectively, by the beam 35 and rear bar 33.

44 indicates a brace-strap, which is approximately semicircular in shape, one end eing bolted to the outer or rear end of the rear bar 33 and the other end to the outer or rear end of the front bar 32. The strap 44 is provided with an upward-projecting por-..

tion 44*. v 45 indicates a brace, one end of which is bolted or otherwise secured to the bracket 37 and the other end to the upper portion of the upward-projecting portion 44*of the bracestrap 44. 46 indicates a caster-wheel journaledin a The fork 47 is provided with an upward-projecting post 48, which is journaled in the sleeve 41.

49 indicates a spiral spring, which is contained in the sleeve 41 above the post 48, and is secured to and bears upon a swivel 50 on the u per end of the post 48. The other end of t 1e spring 49 is looped around and bears upon a pin 51, which is inserted. through suitable openin-s 52 in the sleeve 41. As shown in the rawings, there are several of these openings arran ed at differ-- ent istances from the top of t e sleeve 41, whereby the position of the s ring and of the caster-wheel may be varied y inserting the pin 51 in one or the other of said openings.

The spririg 49 thus affords a suitable springseated'bearing for the caster-wheel 46; and

it is obvious that the hei ht at which that end may be carried from t e ground may be adjusted by the adjustment of the pin 51 in the holes 52.

As thus described, it is obvious that the rake-frame of the machine is sup orted at its forward end by the carrying-w eel nearest the plate 29, and that the other end of the rake-frame is'supported by means of the caster-wheel 46; and that by means of the bar 35 and its connections above described the rake-frame will also be supported by the other carrying-wheel 14; thus affording a triple support for said rakeframe,-that is to say, the two carrying wheels and the caster-wheel.

53 indicates a shaft, the outer end of which is journaled in a suitable-bearing on the end bar 31 of the rake-frame. The other .end of said shaft 53 journaled in a slide box 54, supported by the plate 29, and best shown in igs. 3, 4 and 5. The slide-box it is secured to t consists, as is best shown in said figures, of a journal portion 55,in which one end of the shaft53 turns, as above set fortl ----a forwardrojecting portion 56 and a lower portion 57. he journa ing portion 56 are preferably formed integrah as is shown in F ig.,5,,and the parts 55 and 56 are fastened to the lower portion 57 by means of screws 58. The lower part of the forwardprojecting portion 56 is adapted to rest within and slide longitudinally of itself ina suitable slot 59 in the plate 29, and isheld in place-in'said slot by means of the lower portion 57 being broader than the slot and projecting beyond its sides, as is shown 'in dottedlines in Figs. 3 and 4 60 indicates a spiral spring, which bearsat one end upon the sliding box 54 and at the other endupon a cross-p1ece 61 in the slot 59.

The spring 60 by its expansion tends, to normally force the parts backward toward the rear end of the slot. The lo'wer'portion 57 is provided with a downward-depending lug 62. 63 indicates a connecting rod, one end of which-is secured to the lug 62 and the other endto 'a erank-arm 64 on a pin- 65 which is journaled in the front portion of the plate 29. 66 indicates a lever which is provided with a head 66%. The head 66 is provided with a suitable o ening b means of which be top Q the pin 65. By

means of the turning of; the lever 66, the crank-arm 64 is rotated, andflby means of the connecting rod 63 the sliding 'ournalboX 54 may be moved forward upon t e plate 2-9, so as to cause the engagement, of the gear is further held in position by means of aprojecting finger 67, which 1s secured to 'or formed integral with the plate 29 and. projeets backwardabove the ournal-box 54, as is best shown in Figfill, so that the journalboX slides between the lower portion of the finger 67 and the surface of the late 29.

1 68 indicates a beveled gear, w ich is keyed portion 55 and forward-projeetto or otherwise secured upon the forward' end of the shaft 53, and isadapted to engage and mesh with the gear 26,- when the parts are thrown into engagement by the' opera tion of the lever above described, whereby when the gear 26 is rotated by the action of the carrying wheels 14, as above described, the sl'iaft 53 will be rotated with it.

The shaft 53 carries upon its ends spiders 69-;-70.. The spider 69, as is best shown in Fig. 7, is shaped'so as to house and carry three sets of gears 71-72. The gears 71 are journaled upon the spider 69. The gears 72- are keyed or otherwise secured to the endsof shafts 73. Theshafts73 are journaled in the spiders 69 and 70.

74 indicates a stationary gear which as shown in Fig. 7, is of the same diameter as the gears 72, and is loosely journaled upon the shaft 53 against the outer surface of the spider 69 and centrally thereof, so as to mesh with the three gears 71. The gear 74 is located, as is best shown in Figs. 3 and 4, between the outer surface of the spider 69 and the adjacent edge of the plate 29, and is provided with two lugs 7576, which are adapted to bear against the upper surface of the plate 29 and prevent the rotation of the gear 74.

77 indicates bars, which are secured a short distance from the shafts 73 by means of blocks 78 and pins 79 passing through the bars 77 and the shafts 73.

80 indicates rake-teeth, which are located at suitable intervals along the shafts 73 and are secured thereto by coiling their. upper ends around the shafts 7 3 and then the short ends left after the coiling t irough the bars 77, thus giving the teeth proper resiliency and spring.

It is obvious that when the shaft is rotated by the action. of the carrying wheels 14, as above described, it will carry with it the spiders 69-70, thus revolving the rakecarrying bars 73 around the axis of the sh aft 53. At the same time, the gear 74 being stationary, as above described, by means of the 7172 the rake-teeth 80 will be maintained constantly in the same vertical position throughout the entire revolution, caus ing them to engage the scattered hay, or other material to be raked, and move it forward into \vindrows as the machine is driven forward.

indicates guards. The guards 81 are approximately semicircular in form, as best shown in Fig. 9, and are secured to the front and rear bars 32-33. The function of the guards R1 is to cause any hay that might otherwise not be freed from the. rake-teeth to be freed therefrom as the rake-carrying bars revolve.

It will be noticed, from the above description, that the rake-teeth, when they come into position to engage the hay, descend into the hay substantially vertically, and, engaging the hay, move forward still in a vertical position, and, when they have reached their extreme forward point inthe rotation, risc vertically from the hay, insuring a much better distribution of the hay into windrows than could be the case if the rake-teeth were not constantly held in said vertical position during their rotation about the shaft 53. It is also obvious-that when it is desirable to drive the machine along without operating venting'the ra .e from being rotated, W ien itds-desired to have the rotating rake operate, to rakezhayor other material, said gears are thrown. into engagement by swinging the said lever in' the op osite direction. 4 From the'above description it will be see assing same end of the rake-frame, is supported by the bracket 37, which, as is sai above, is connected with the front bar 32 of the rak e frame, and with the beam 35. The beam 35,

being connected as above described with the extreme rear corner of the rake-frame, and being connected at lts' front end with the bar '16 by means of the clip 36,, will rigidly hold the bar 16 and prevent its turning. The cross-bar 16 of course is madesufficiently strong to resist torsional strain. The extreme front corner of the rakeframeis'supported, as is said above, directly upon the plate- .39. The other front corner, nearest the driving-wheel, is supported by being secured to the plate 29, which is secured by meansof the clip 1Z9" to the bar 16. The bar It), being rigidly held and prevented from turning. will, by means of this, connection,

firmly .hold the plate 29, which will thus act as a support for the forward corner of the rake-frame nearest the driving-wheel. The rake-frame is thus thoroughly supported at all its points upon the three points of su 'port,to wit, the two driving-wheels and t to caster-wheel.

I have shown the cross-bar 16 as being rectangular in section and the several parts secured thereto by clips which fit the said rec it is obvious, however, that a tangular bar. bar of any polygonal cross-section might be used, with 'clips to correspond, or even that the bar might be made circular or of any other suitable sha e in cross-section and the clips keyed. or bo ted or otherwise secured thereto, and the-same end be accomplished and I therefore do not wish to limit myself to the use of a bar rectangular in section, with clips shaped to correspond thereto.

l. have shown the revolving rake of my device as rovided with three rods carrying rake-teet and this is the form in which I prefer to construct it. It is obvious, however, that it might be provided with more or.

less than three rake-tooth carrying-rods with-- out departing from the spirit of my inve'n-' tion, and I therefore do not confine myself to that number of bars for carrying the raketeeth of the revolving rake.
